Note – If a fan failure message appears in the rmlog.log, replace the fan FRU that
was reported to have failed (controller or power supply fan) even if the fan appears
to be spinning. The fan circuitry has an RPM sensor which triggers the fan failure
message. The fan may continue to spin but in a degraded mode (at half speed).
